Notes:
- Input or output selected from front panel.
- Specified video S/N ratio from -40 dBm to -10
dBm.
- This range may be extended with an appropriate
RF attenuator.
- These characteristics are independent of input
level from -40 dBm to -10 dBm, and channel frequency.
- Measured using SINE X / X, relative to North
American M system pre-correction; 200 kHz (reference)
to 4.0 MHz, including ripple.
- Video signal-to-noise ratio measured with aural
carrier present.
- Operation down to an RF input level of -48 dBm
practical with some increase in video noise.
- The I & Q outputs have matched
800 kHz low-pass filters.
- Measured with full field modulated ramp.
- Balanced, transformer coupled.
- Headphone output provided on switchboard quality
tip, ring sleeve (TRS) three wire type phone jack.
Tip and ring sourced separately to drive both ears
of stereo headphones. Either tip or ring may be
shorted as would happen with monaural headphones
using a tip, sleeve (TS) two wire type phone plug.
- Measured using a Modulation Sciences,
Inc. STV-784 Television Stereo Generator and a Modulation
Sciences, Inc. SRD-1 Stereo Reference Decoder. All data
gathered in BTSC Equivalent Mode, quasi parallel detection.
- 0 dB reference = 55 kHz deviation.
- In RF INPUT mode unit receives television channels.
In IF INPUT mode, IF INPUT / OUTPUT BNC connector
switches from being an IF output to being an IF
input. The entire RF input portion is disabled
in IF INPUT mode.
- The serial data interface is modified to permit
daisy-chaining up to 9 units on one circuit. Each
msi 320 has a user assigned address code.
All units supplied with aural notch SAW filter assembly.
